But a reduction in the number and intensity of large hurricanes driving ocean waters on shore — such as this month's Hurricane Joaquin, seen, which reached category 4 strength — may also play a role by cooling sea - surface temperatures that fuel the growth of these monster storms, the team notes.

Even as the surface warms, the deeps remain cool, and this cold water will continue to periodically push the ocean out of the El Niño state.

The warming of the oceans by sunlight, makes the daytime surface waters more bouyant than the cooler waters below and this leads to stratification - a situation where the warmer water floats atop cooler waters underneath, and is less inclined to mix.

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

In general, the regions of expanding warming upwelling water in the Indian Ocean, North Pacific, or wherever they are, must create slight bulges in the surface, and the regions of shrinking, cooling, sinking water in the Arctic must create slight depressions in the sea surface (again, I mean in a very low pass sense — obviously storms, tides, etc, create all kinds of short - terms signals obscuring this).

and, of course, the effect of cooler water at the ocean's surface is less re-radiation of heat into the atmosphere over it, and hence (i) less heating of the atmosphere from that source (ii) more heat retained at that water surface.

for the oceans there is the possibility of «surface» (100 to 200 m thickness) ocean waters to cool stronger than forecasted.

If the correlations were positive, that temperatures matched Scenario B, would you accept skeptics saying, «Sure, but really, Scenario C is more useful», and if the ocean - heat data looked like Lyman (2010), them saying «Sure, but that's only because deeper heat is being transfered to the surface and replaced by cooler waters, but we can't see it»?

IF cool deep sea water were mixed relentlessly with surface water by some engineering method --(e.g. lots of wave operated pumps and 800m pipes) could that enouromous cool reservoir of water a) mitigate the thermal expansion of the oceans because of the differential in thermal expansion of cold and warm water, and b) cool the atmosphere enough to reduce the other wise expected effects of global warming?

When upwelling brings cold water to the ocean's surface, cooling the atmosphere, where is that heat lost from the atmosphere «hiding»?

So, if each underwater artic volcano emitted 1 km3 a week (a rather large average flow) and did it for a year (about 52 weeks) you would need about 620 very active and extremely powerful volcanoes in order to warm the artic ocean by just 1 C (and that ignores surface cooling, in / out water flows and time rates that would require even more volcanoes.)

The heat sink is the cold bottom water which the heat engine can pump up to cool the ocean surface and the overlying atmosphere.

The real problem here is that this AMO explanation was picked up and broadcast by the press in a very uncritical manner, usually in these terms: «Surface waters of the Atlantic ocean warm up then cool down in long, subtle cycles.

When this salty surface ocean water is cooled sufficiently, it becomes too dense to float above the waters it overlies, so it sinks «like a rock».

In addition to reducing greenhouse emissions, we can upwell cold water and nutrients to cool the surface and increase ocean food production.

eadler2 January 10, 2015 at 5:54 pm ... When ocean surface temperatures cool, due to a La Nina, the warmer surface water is mixed deeper into the ocean and cooler ocean water flows along the surface of the Pacific.

While the aerosol influence last less than a decade, the influence on surface temperatures continues because of the slow mixing of cooled waters on the ocean surface.

When ocean surface temperatures cool, due to a La Nina, the warmer surface water is mixed deeper into the ocean and cooler ocean water flows along the surface of the Pacific.

In addition to expending some of the oceanic heat, the wave action of the cyclone tends to mix the cooler ocean waters below toward the surface, reducing sea surface temperatures after the cyclone passes.

Warmer air holds more water vapour so that warmer air will extract more vapour from the ocean surface thereby cooling the ocean surface..

It's because both land and ocean surfaces are heated by shortwave solar radiation and where aerosols reflect SWR equally well over land or water and where greenhouse gases work by retarding the rate of radiative cooling which is not equal over land and water.

Only in certain regions, notably in the Antarctic and northwest Atlantic Oceans, does a combination of evaporation (which increases the water's salt content) and wintertime cooling make surface water dense enough to sink all the way down.

All the sea surface water, warmed by the tropical sun, is blown to the west of the Pacific and, to compensate part of the imbalance, cooler deep ocean waters well up on the western shores of Latin America (and spread all the way up to the Solomon Islands).

Due to the Antarctic Refrigerator Effect, the deep oceans continued to cool, and the thermocline that separates warm surface water from cooler deep waters became increasingly more shallow.

Subsequently, climate change has been greatly affected as Antarctic Intermediate Water have cooled and exerted a tremendous effect on tropical sea surface temperatures for millions of years via «ocean tunneling».

In addition, the overturning of the ocean constantly brings new water to the surface, to radiate and to cool.

As warm surface currents near the poles the water cools and its salinity increases due to ocean water freezing and leaving the water near the poles more salty.

Water takes longer to heat up and cool down than does the air or land, so ocean warming is considered to be a better indicator of global warming than measurements of global atmospheric temperatures at the Earth's surface.

It seemsthe observed increase in trade winds lead to the surfacing of cooler waters in the Eastern Pacific ocean and this phenomenon is found by models to cause global average temperatures to cool.

A simple model of this process is an increased vertical circulation in the ocean, such as an enhanced PDO, that brings cooler water to the surface faster and sequesters the warmer water faster.

It's what causes the topmost millimeter of the ocean's surface to almost always be 1C cooler than the water below it.

However, the ocean surface will eventually freeze (on the much longer timescales needed to cool the entire water column to freezing).

Um... while the oceans as a whole would have to cool, the sea surface would have to warm up substantially in order to transfer lots of heat to the air (and in order to warm up substantially, I suppose there would have to be reduced circulation with cold deeper waters).

Second, the ocean absorbs CO2 on average all across the lower density surface as the waters cool by radiation to space on their return to the poles.

AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing water mass from equatorial latitudes and transporting this water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..
